Motivational interviewing as a clinical decision-support skill in time-limited practice

To reconceptualise motivational interviewing (MI) as a clinical decision-support skill for time-limited healthcare encounters and to clarify how this framing assists clinicians in navigating behaviour change without extending consultation time or compromising therapeutic relationships.

This discussion paper uses a narrative and conceptual synthesis approach integrating foundational motivational interviewing theory, systematic reviews and meta-analyses in healthcare settings, and implementation and fidelity literature relevant to routine clinical practice. Literature was identified through iterative searches of PubMed and reference lists of key publications, including targeted retrieval of fidelity and implementation research. The objective was not exhaustive evidence synthesis, but clarification of how motivational interviewing may function operationally within time-limited clinical workflows and behavioural decision-making.

Motivational interviewing is associated with modest but clinically meaningful improvements across selected behavioural domains, including medication adherence, lifestyle modification, substance use risk reduction, and engagement with mental health treatment. Effects vary according to clinical context, clinician skill, fidelity to motivational interviewing principles, and implementation conditions. Beyond effect size estimates, reframing motivational interviewing as a readiness-calibrated clinical decision-support skill highlights its practical contribution to communication processes in time-constrained settings. Conceptually, motivational interviewing provides a structured framework for engaging patients, clarifying focus, eliciting intrinsic motivation, and planning next steps when readiness is present.

Motivational interviewing should not be regarded as a substitute for guideline-directed care, pharmacological treatment, psychotherapy, or structural interventions. Rather, it functions as a complementary clinical skill that supports patient engagement, preserves autonomy, and aligns care with readiness within time-limited encounters.

When conceptualised as a decision-support approach rather than a counselling technique, motivational interviewing offers clinicians a pragmatic method for determining whether to pursue action, explore ambivalence, or defer change. This framing has implications for postgraduate training and continuing professional development in patient-facing disciplines where behaviour change is central to care.
